Mona grew up with four younger brothers. She was a college student before the mutagen bomb transformed her. Since she is no longer able to attend, she spends her time helping the impoverished of Mutant Town, which includes stealing food from Mutanimals warehouses to bring back to Alopex's shelter. Jennika came to her rescue on one such occasion, and the two struck up a friendship before being forced to defend themselves from Bandit and Puggle.
After Sally called off the goons she took the food back to the shelter were she, Jenny, Raph and Alopex listened to Sally talk about problems with the Mutanimals.
Mona accompanied Sally Pride and Jennika in their pursuit of the weasels, and seemed charmed by their childlike behavior. She was particularly outraged when it was discovered that Hob was trafficking the weasels to the Foot Clan, and helped bring them back to Alopex's shelter. She was extremely enthusiastic about meeting Donatello, having already been impressed by Raphael's ninja prowess.
After the four Turtle brothers were reunited and returned to Mutant Town, Mona accompanied them, Alopex, Sally and Jennika to a heavy metal concert, arriving arm-in-arm with Donatello at Kennel Klub.
Mona came to help Alopex with babysitting the weasels.While playing with them she told Alopex about her family. In the morning, while waiting for the turtles, they made breakfast and talked about how they could improve Mutant Town.
Donatello came to see her while he was renovating a derelict building in an effort into making it Mutant Town's first school. But several mutants who had been squatting in the building confronted them. Their leader, an orca named Jo, attacked Don in an attempt to force him and Mona out of the building. As Don defended against Jo with his bō, he offered to set them up with necessities and amenities, piquing their interest when he mentioned internet and electricity. As it turns out, the mutant squatters had been trying to contact their families on the outside to no avail. Jo accepted the offer and Don set up their internet. Mona went off to meet Jennika and Sheena to discuss Sheena teaching a music class at the school, and she gave Don a peck on the cheek as she left. As Mona passed the dōjō, Lita ran out and said she can't find Jenny. Mona said she's on her way to meet with her and allowed Lita to tag along if she's careful, as the Kennel Klub is only "for grown-ups." Later that night in Jennika's room at the dōjō, Mona, Jenny and Sheena talked about music, unaware that an intruder had snuck by Jenny's bedroom door.
After her internet had been reconnected, Mona finally mustered enough courage to contact her parents, also wanting to reveal and explain her new appearance through a video call. But when they saw her as a mutant salamander, they immediately panicked and ended the call. It was then Sally came for a visit and and a crying Mona ran out to hug her for much needed comfort.
When she and Donnie were at Aloplex’s shelter she asked about his family and was shocked to learn the Donnie and hi brothers were never human and about there past lives. When Mona was in support group she was outraged by the fact that there were Mutanimal supporters in the group with escalated into a fight.
